General Safety Guidelines

Operating a chainsaw can be dangerous if proper precautions are not followed. Adhere to these general safety guidelines:

• Always inspect the chainsaw before each use for any damage or loose parts.
• Ensure the chain brake is functional.
• Operate the chainsaw only in well-ventilated areas.
• Keep bystanders, children, and pets at a safe distance from the work area.
• Do not operate the chainsaw when fatigued or under the influence of alcohol or medication.
• Maintain a firm grip with both hands on the chainsaw handles.
• Be aware of kickback risks and how to avoid them.

Setup and Assembly

Before operating your McCulloch CS 42S chainsaw, proper assembly and preparation are crucial.

Unpacking and Initial Inspection

Your chainsaw package includes: 1x McCulloch CS 42S petrol chainsaw and chain. Carefully remove all components from the packaging and inspect for any shipping damage. If any parts are missing or damaged, contact your retailer.

Chain and Bar Installation

1. Ensure the engine is off and the chain brake is engaged.
2. Remove the chain cover nuts and the chain cover.
3. Place the chain around the sprocket and guide bar, ensuring the cutting edges face forward on the top of the bar.
4. Mount the guide bar onto the studs, aligning the chain tensioner pin with the hole in the bar.
5. Replace the chain cover and loosely tighten the nuts.
6. Adjust chain tension using the tensioning screw. The chain should be snug but still able to be pulled freely by hand.
7. Fully tighten the chain cover nuts.

Fuel and Oil Mixture

This petrol chainsaw requires a specific fuel-oil mixture. Refer to the fuel tank cap or a sticker on the machine for the exact ratio (e.g., 50:1 or 40:1). Use high-quality unleaded petrol and a suitable 2-stroke engine oil. Mix the fuel and oil in a separate, approved fuel container before pouring into the chainsaw's fuel tank.

Fill the chain oil reservoir with appropriate chain lubricant. Never operate the chainsaw without chain oil, as this will damage the chain and bar.

Operating Instructions

Follow these steps for safe and effective operation of your McCulloch CS 42S chainsaw.

Starting the Chainsaw

The chainsaw features a soft-start system, which reduces resistance in the starter cord by up to 40%, making starting easier.

1. Place the chainsaw on a firm, flat surface.
2. Engage the chain brake.
3. Set the choke (if cold start) and prime the fuel system (if applicable).
4. Pull the starter cord firmly until the engine fires.
5. Disengage the choke (if used) and pull the cord again until the engine runs smoothly.
6. Allow the engine to warm up for a few moments before disengaging the chain brake and beginning work.

Cutting Techniques and Safety

The McCulloch CS 42S is equipped with an OxyPower engine for demanding cutting tasks and features anti-vibration technology for comfortable use over longer periods.

• Always maintain a balanced stance and firm grip.
• Never cut above shoulder height.
• Be aware of the direction of falling timber and clear escape routes.
• Avoid cutting with the tip of the guide bar to prevent kickback.
• When cutting logs, ensure they are stable and supported to prevent rolling or pinching the bar.

Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your chainsaw.

Periodic Maintenance

• Clean or replace the spark plug.
• Clean the cooling fins.
